Description

technical field [0001] The invention relates to the field of temperature measurement, in particular to an algorithm and system for stabilizing the temperature test value of a temperature sensor. Background technique [0002] At present, due to the calculation of the object temperature in the field of view, it needs to be calculated according to the temperature of the sensor. If there is a deviation in the temperature read out, the measured physical temperature in the field of view will also be inaccurate, resulting in inaccurate temperature measurement, which can easily lead to Misreporting of temperature measurement results in many diagnostic deviations. [0003] In addition, due to the influence of communication reasons or the error of the sensor itself, the acquired temperature of the sensor has a relatively large error, which eventually leads to inaccurate measurement.
